1964 R. MIGNEAULT ETAL GLAZING STRIP AND ARTICLE EMBODYING SAME FiledFeb. 11, 1963 VENTOR PATENT AGENT United States Patent 3,144,689 GLAZINGSTRIP AND ARTICLE EMBODYKNG SAME Romuald Migneault and Fenland W.Migneault, both of 332 St. Andre St, Gatineau, Quebec, Canada Filed Feb.11, 1963, Ser. No. 257,642 1 Claim. (Cl. 20-564) This invention relatesto glazing strips for use in glazing wood sashes and the like.

The use of plastic composition glazing strips in conducting glazingoperations in metal frames and sashes is widespread. However, the commonand universal manner of glazing glass panels in conventional wood sashesand frames involves the use of putty and the like and no satisfactorypreformed glazing strip for glazing wood sashes appears to haveheretofore been provided.

It is an object of this invention to provide a preformed glazing stripfor use in glazing wood sashes, such strip being of simple andconvenient manufacture, easy and rapid to install Without special skill,and fully effective in providing adequate sealing and position-retainingcontact with its glass and wood engaging surfaces.

Another object is to provide a glazed wood sash having a preformedglazing strip incorporated therein without use of separate fasteningelements.

The invention will be described with reference to the accompanyingdrawing, in which FIGURE 1 is a perspective view of a glazing strip inaccordance with the invention,

FIGURE 2 is a partial elevational view of a glazed sash in accordancewith the invention, and

FIGURE 3 is a section on line 33 of FIGURE 2.

The glazing strip in accordance with the invention is preferablyproduced by extrusion from a plastic composition material. The plasticcomposition material may be polyvinyl chloride, polyethylene, or thelike. Preferably, it is of soft, pliable, rubber-like form.

The strip 10 may be about /1 inch in width with an overall thickness ofabout A inch, and this dimension will usually be satisfactory for mostglazing operations. The strip is of uniform cross-section and has a mainbody portion 11 which gradually increases in thickness from asubstantially sharp longitudinal forward edge 12. Portion 11 has aslightly convex outside surface 13 and a slightly concave inside surface14. Body portion 11 is thus generally triangular in cross-section.Surface 13 terminates in a rearwardly directed lip 15 which constitutesa portion of a shoulder 16. A base portion 17 extends rearwardly fromshoulder 16 adjoining surface 14. Base portion 17 has two pairs ofopposed barbs 18 directed forwardly towards forward edge 12. It will beapparent that two of the barbs are in opposed relation to shoulder 16and the other two project outwardly from surface 14.

Referring to FIGURES 2 and 3, the glazing strip described is employed toglaze a wood sash 19 with glass panel 20. The sash 19 comprises sections21 each having the usual glass panel seating shoulder 22. Each sashsection also has a groove 23 in parallel relation to shoulder 22 and inthe contiguous sash surface 26 perpendicular to the shoulder. Eachgroove is of rectangular crosssection and is defined by opposed sidewalls 24 and a bottom wall 25. One side wall 24 is disposedsubstantially in the plane of the outer surface of glass panel 20.

"ice

While the groove may have any suitable dimensions, it has been foundthat one Ma inch wide and inch deep is quite satisfactory.

The glazing strip 10 is applied by cutting appropriate lengths thereofand inserting the base portions 17 into the grooves 23, the joints beingmitred as shown. Surface 14 of each strip length, by reason of the factthat it is initially bowed or concave and because the wall 24 of groove23 is in the same plane as the glass surface, will be constrained toflatten out and sealingly engage such glass surface. The edge 12 is inparticularly snug contact with the glass surface to eliminatepossibility of any leakage therepast.

It will be apparent that the barbed base portion 17 has a rearwardextent substantially equal to the depth of groove 23 whereby shoulder 16engages the sash surface 26. As shown, shoulder 16 flattens against suchsurface and, since lip 15 initially projects rearwardly, it will snuglyand sealingly engage the surface 26 to prevent any leakage therepast.

Insertion of the barbed base portion 17 into groove 23 is designed tocompress the barbs 18 thereof as shown in FIGURE 3. The undistortedoverall thickness of the portion 17 may be about one-sixteenth inchgreater than the width of groove 23 to provide the required compres-vsion of the barbs. The base portion 17 holds the glazing strip inposition but permits removal thereof in the event that reglazing isnecessary.

Glazed sashes, as described, have been found to be fully as effective asconventional putty-glazed sash in actual use. Indeed, the life of sashesglazed in accordance with the invention is much longer since, of course,putty glazing deteriorates with age.

Probably the most important advantage of the invention resides in thefact that glazing in accordance therewith may not only be carried out byunskilled labor but the time required to effect the operation issignificantly reduced with consequent substantial saving in labor costs.The replacement of broken glass panels is also greatly facilitated byuse of the glazing strips described.

We claim:

A glazing member comprising an elongated, pliable, un tary strip ofplastic composition, said strip being of uniform cross-sectionthroughout its extent, said strip having a forward body portion and arearward base portion, said body portion having a convex outer surfaceand a concave inner surface, said surfaces converging towards each otherand terminating in a common longitudmal edge of said strip, said stripalso having a longitudinally extending shoulder at the juncture of saidbody and base portions and offset from said juncture, said shoulderhaving a transversely concave surface having a terminating edge definedby its line of juncture with said convex surface of said body portion,said base portion having compressible barbs projecting from each sidethereof, said barbs on one side of said base portion being 1n opposedrelation to said shoulder.
